HOME MOVIES FOR DECEMBER PAGE 525 provides a pair of grooved wooden strips to permit using it on my titler ; also there are two holes in the base for mounting two lengths of wood dowel at the front as supports for my special home-built effects-box, filter holders, etc. The basic part of this shift-over platform is the flat metal plate on which both camera and critical focuser are mounted; and here it is important to remind that the critical focuser must be so mounted upon this plate that the camera lens, when removed from camera and mounted upon it, is at the same identical distance from subject as when mounted on the camera. This plate is bent at each end and two round notches cut out to receive the two metal rods on which it slides laterally. The two rods are mounted upon another metal plate, the ends of which are turned up, as may be seen in Figs, i and z. This second plate may be drilled and tapped to receive the tripod screw, or mounted on the secondary base as described above. Determining the extent of lateral shift of the top plate will depend upon the make and model of camera for which the focuser is built. Adjustments should be so made that when the camera is shifted to the left (as seen from behind camera) its lens will be in the exact position it occupied when mounted on the focuser and the focuser was in viewing position. A simple method which I followed in determining this lens position was to mount the camera and focuser on the sliding base, placing them in the approximate center of the stand. Stand was then placed on the floor near a wall with the lens facing and almost touching the wall. With the camera in taking position, outline of lens was penciled on the wall. Lens was then mounted on critical focuser and the focuser shifted to the right until the lens barrel was exactly opposite the penciled mark on the wall. This determined the exact position for viewing with the focuser, and stops were placed on the slide rods to so guide shift of the sliding plate thereafter. With this gadget, centering camera on title cards is no longer a risk. And when I want to shoot ultra-closeups, I can focus with the same precision as obtained with the reflex focuser on the expensive Cine Special. It is worth every r inute and every nickle it cost to build. Synchronized Sound On ^bhc . • . • Continued from Page 510 speed of 780 R.P.M., which gave me 13 frames per second. I decided to utilize the slow film speed to give me a longer "take" before having to reload. Incidently this worked out very well by using an 8" record for a single roll or a 10" record if the mechanism is stopped and the camera reloaded. By splicing one roll to another, synchronization is retained exactly to a frame. The standard 16 f.p.s. speed could be obtained had I taken the trouble to search for gears of correct ratio; but it must be remembered that this was in the nature of an experiment and the slower speed of 13 f.p.s. would detract nothing from either picture or sound quality in the finally projected films. The altered camera, as assembled with the recorder for the purpose of shooting and recording a scene, is shown in Fig. 1. The camera is coupled directly to the record turntable by a solid shaft and gears. In filming a scene, the recorder switch is snapped on causing the turntable and camera to start turning simultaneously. Obviously this experimental hookup presents some limitations in camera movement, none of which cannot be overcome by further development and improvement. Method of coupling camera with the turntable was comparatively simple. As shown in Fig. 3, the large 80 tooth camera gear was stripped of the motor spring and provided with a longer shaft that would extend far enough beyond the camera case to permit coupling the shaft and gears leading to the turntable. Holes were drilled in the bearing plates to permit meshing with both the 8 tooth cam gear and the 12 tooth rewind gear. These were the only camera gears used. Having access to a lathe, I made small bronze bushings for the new bearings. In my first experimental hookup, the camera was driven by a short flexible shaft extending from center post of turntable to the camera gear shaft. I have since replaced this with the solid shaft, as pictured, by using the speedometer gear housing seen in Fig. 1 and shown in detail in the first diagram. The recorder to which camera is thus coupled was assembled from an old public address amplifying system and a General Industries turntable and cutting head. A strap iron bracket extending from side of the carrying case, holds the camera in proper position, being attached to the camera by means of a tripod screw. Pictures may thus be taken with this arrangement with the sound synchronized on disc so that it is possible to obtain exact lip-synchronization. After pictures are taken and the films processed, the next step is to project them with the recording synchronized GLAMOROUS! Stars galore . . . Ravishing beauty . . .
